Abstract: A liquid herbicide container having a closed end connected to a long handle and an open end coterminous with an externally threaded outlet conduit includes a spring biased pump inserted within the conduit into communication with the container body. A threaded cap is held rotatably captive with an open flange end of the pump and sealingly engages the flange with the threaded outlet conduit. Reciprocally captive within the pump, a discharge tube extending from the open flange end actuates the pump to withdraw the herbicide. A hollow coupler connected to an applicator pad has an open end adapted to slidably receive the cap and flange over an incursive distance adjustably limited by an annular ledge within the coupler, functioning alone or in combination with at least one resilient washer overlying the ledge.
